Can't access device manager in win 7

Last Modified: 2012-08-14
Hi Everyone,

I don't seem to be able to access the device manager in my win 7 machine.  What made me notice was my network card stopped working.  So to check it I went to device manager to check it out, and it won't let me but comes up with following error:-

"MMC cannot open the file C:\Windows\ystem32\devmgmt" (Evn though win 7 is running in 64 bit.

Can anyone help?
